Patent EP-0137421-A3 (EP)
IPC: F01C1/20
Filed: 1984-09-27
Abstract: An external shaft rotary piston machine wherein pistons of a piston rotor run in engagement with a cavity of a circular cylindrical sealing rotor during a particular relative rotational position of the rotors, the cavity being substantially larger than necessary for passage of the pistons in order to avoid flow losses due to seal wedging flow and compression. In order to avoid overflow from the high pressure side to the low pressure side of the machine through the sealing rotor while the pistons move in the sealing rotor through the space defined by the cavity, a sealing effect is created by a leading edge and a trailing edge portion of the opening of the cavity of the sealing rotor moving along a leading and a trailing side surface of the pistons. This is effected kinematically due to the fact that the trailing edge of the cavity opening is displaced radially inwardly and that an edge portion extends from the trailing edge convexly relative to the peripheral surface of the sealing rotor.

Abstract: The loading of a variable-capacity compressor in an air 
conditioning system is varied in accordance with evaporator 
pressure at return air temperatures above an upper set 
point and is fixed in the region of 33% when the return air 
temperature falls below the upper set point. The evaporator 
is coupled to the compressor and air is passed over it to 
remove heat from the air while evaporating working fluid, 
the pressure of the working fluid being detected by a switch 
(72) forming part of the compressor control circuit. The air 
temperature is monitored by thermostats (14, 12) respon­
sive respectively to the upper set point and to a second 
lower set point, below which the compressor is shut down 
and heating apparatus is automatically and momentarily 
activated. The compressor is not activated again until the 
temperature rises above the upper set point. The heating is 
de-activated as soon as the temperature rises above the 
lower set point.

Z-axes through the origin, the shaped beam antenna is 
characterized in that the longitudinal axis of each reflector 
segments is in parallel with the X-axis, the main reflector is 
symmetrical with respect to the X-Z plane and formed 
convex in a negative direction of the Z-axis, and each 
radiating element is disposed so that its excitation amplitude 
is symmetrical with respect to the Y-Z plane and its excitation 
phase is antisymmetrical with respect to the Y-Z plane,

Patent EP-0213846-A3 (EP)
IPC: H04L27/26
Filed: 1986-08-14
Abstract: A method for the generation of precise single- and dual-tone 
multiple-frequency signals using only digital signal processing 
techniques is disclosed. The frequency, amplitude and cadence of 
the tone(s) generated are programmable via a microprocessor. The 
tones generated are suitable for the dual-tone multiple-frequency 
(DTMF) used in communication networks as well as for tone message 
and tone ringer functions. The principle of operation is that a 
triangular wave is produced (820, 826) by the repetitive addition of a 
user-supplied "delta" value to an accumulator until an overflow 
condition occurs, and then the delta value is repetitively 
subtracted from the accumulator until an underflow condition 
occurs. Next, a trapezoidal wave is produced by multiplying (822, 828) the 
triangular waveform by 1.5 and truncating the resulting waveform 
at selectable positive and negative levels. The desired 
amplitude is then established by multiplication by a selectable 
attenuation (824, 830) value. A DTMF waveform is obtained by generating two 
waveforms as just described and then summing (832) the resulting 
waveforms, producing a waveform of a frequency with less than 
1% deviation. An exemplary embodiment illustrates the waveform 
generation method of the present invention in the audio processor 
section of a digital subscriber controller.

Title: Carburetter for an internal-combustion engine and idling system therefor
IPC: F02M3/12
Filed: 1987-02-13
Abstract: A carburetor with an idling system is designed so that the full pressure differential or gradient available between approximately ambient pressure and the vacuum in the intake tube is employed for producing a critical pressure ratio of a supersonic flow in a laval nozzle. To make this possible, a fuel air emulsion formed with primary air is introduced from a mixing duct via a constricted orifice of a tubular nozzle at a bore constriction, at which there is always a sonic velocity when there is a critical and supercritical pressure ratio, into the secondary air flow where it is superfinely atomized in the secondary air flow, with a maximum velocity differential, aided by subsequent pressure surges. At least at a point far into the partial load range of operation, the idling system produces a homogeneous mixture which is homogeneously distributed in the intake tube with a practically molecular state of division so that it is even supplied to all cylinders of the engine and completely combusted with a minimum production of contaminants.
